RADIATOR-TUBING.

Specification of Letters Patent. Application filed September 29- 1904 Serial No. 226 .485.

' To all whom itmay concern:

Be it known that I, FRANK H. STOLP, a citizen of the United States, residing at Chicago,

county of Cook, State of Illinois, have invented a certain new and useful Improvement in Radiator-Tubing, and declare the following to be a full, clear, and exact descri tion of the same, such as will enable others s 'lled in the art to which it pertains to make and use the same, reference being had to the accompany-.

ing drawings, which form a part of this specification,

My invention relates generally to heat radi ators, and more particularly to devices for dissipating the heat of and thereby cooling a circu ating' fluid. I

- It is necessary that the cylinders of engines, especially of the ex losive type, should be surrounded by a j ac et between which and the cylinder a cooling fluid circulates to absorb the heat generated in the cylinder and prevent the latter from becoming unduly heated. In order that the heat absorbed by I the fluid may be dissipated the fiuidcirculates through a cooling device, suchfor instance as a radiator, by means of which the temperature of the fluid is so reduced that vwhen it returns through the jacket it again absorbs heat from the cylinder. A form of radiator in common use for automobiles consists in atube communicating withthe water jacket and provided with a number of coils preferably located at the front of the vehicle, the coils being surrounded by projecting points or flanges for radiating the heat;

The primary object of my invention is to provide radiating coils of the type referred to with improved radiating surfaces which will quickly dissipate the he at and thereby greatly lower the temperature of the fluid as it passes through the radiator. I

A further object of my invention is to rovi de improved tubing for radiator coils w 'ch' will be simple 1n construction, inexpensive in manufacture and efficient in use.

My invention generally described consists in a radiating tube the exterior surface of which is surrounded by coiled wire, spirally wound around the tube, the convolutions of the adjacent turns of the coiled'wire overlapping, and means for securing the coiled w1re around'the tube.

. My invention will be more fully described hereinafter with reference to the accompanying drawing in which the same is illustrated as embodied in a convenient and practical and a portion of the tube being shown in elevation.

Reference made of any suitable metal through which the-cooling fluid is adapted to flow from the water jacket around the cylinders of an explosive engine. r

B designates a coiled wire, the convolutions of which are wedge-shaped. The coiled Wire is wound spirally around the tube A and is secured thereto in any suitable manner, such for instance as by brazing. In order to render the connection of thecoiled wire with the tube more secure a tie wire C is preferably located within the convolutions of the coiled wire and drawn tightly around the tube.

By forming the convolutions wedgeshaped an extended engagement with the tube is secured, while the radiation of heat is promoted owin to the convolutions being tapered outwar ly. I The convolutions of ad- 'acent turns of the coiled wire overlap therey increasing the number of turns of coiled wire which it is possible to wind around a given length of tube. The overlapped portions of the convolutions also serve to give greater rigidity and strength to the structure, A retaining wire 0 is preferably. wound around the coiled wire between the convoluch'aracter A indicates a tube Patented Jan. 21,1908 a tions of the adjacent turns, thereby stren thening the convolutions and preventing t eir becoming'bent or flattened against the tube. My improved radiator tubing may be used in any form of radiator, or wherever it is desired to dissipate the heat from a fluid but is articularly designed for use in the manu facture of radiators for automobiles.

From the foregoing description it will beobserved that I have invented an improved tubing for radiators which affords a large ex- .tent of radiating surface and is thereby capable of quickly lowering the temperature of a fluid passing through the radiator.

Having now fully described my invention what I claim as new and desire to secure by.

Letters Patent is:

1-, The-combination with a radiator tube of a coiled'wire s irallywound around and secured to the tu e, the-convolutions of adjacent turns of thecoiled wire being over- 2. The combination with a radiator tube,
